上述终端在所支持的、 与第一小区异频的全部频率上进行测量可以 包括： 终端判断是否需要启动 GAP, 如果是， 则根据 GAP在所支持的、 与第一'■!、区异频的全部频率上进行测量， 并发送 GAP图样给网络侧； 否 则， 直接在所支持的、 与第一小区异频的全部频率上进行测量。 上述发送的第三小区的信息包括： 所述终端根据所述第一小区所属 的基站下发的测量配置信息、 进行同频邻区测量后， 周期性上报的测量 报告； 则接收的第一小区所属的基站反馈的测量配置信息包括， 所述第一 小区所属的基站， 根据所述测量报告中的第三小区标识， 以及自身中配 置的小区关联关系表， 确定与第三小区关联的第二小区， 再根据所述确 定的第二小区的频率信息， 确定的测量配置信息。 在启动终端对第二小区的测量后，如图 la所示， 本实施例进一步可 以包括： 步骤 103、 当测量的上述第二小区的信号质量能够满足上述终端的 业务通信时， 上述终端接入到上述第二小区 。 上述终端接入到上述第二小区具体可以包括： 上述终端接入上述第 二小区， 并断开与上述第一小区的信令连接； 或者包括： 上述终端接入上述第二小区， 并保持与上述第一小区的 信令连接。 上述方案中， 通过部署与第二小区相关联， 与第一小区同频的第三 小区， 使得接入第一小区的终端通过探测第三小区的信令即可确定是否 存在第二小区， 并在确定存在第二小区时， 即对第二小区进行测量， 提 供了与现有技术不同的小区测量方案。 进而， 当上述方案应用于多小区 覆盖重叠场景时， 一方面， 上述方案由于无需持续的进行小区搜索， 降 低了 UE耗电量； 另一方面， 在第一小区为宏小区， 第二小区为低功率 节点小区情况下， 在宏小区信号较好时， 通过应用上述方案也能够启动 对低功率节点小区的测量， 启动测量不受宏小区信号影响， 使得低功率 节点小区对宏小区的分流更加快速有效。 如图 2所示， 本发明另一种信息处理方法实施例包括： 步骤 201、 第一小区的基站接收第二基站发送的所述第二基站所辖 的第二小区和 /或第三小区相关联的信息， 或者接收第二基站发送的所 述第二基站所辖第二小区和第三基站所辖的第三小区相关联的信息， 或 者接收第三基站发送的所述第二基站所辖第二小区和第三基站所辖的第 三小区相关联的信息， 或者接收来自运营管理系统的第二小区和第三小 区相关联的信息； 所述第三小区与所述基站形成的第一小区同频， 所述 第二小区与所述第一小区异频； 步骤 202、 根据所述接收的信息生成所述第二小区与所述第三小区 相关联的信息， 并存储在存储单元中。 较佳地， 上述接收的信息携带在 X2设置请求 （ SETUP REQUEST ) 消息、 X2设置响应（ SETUP RESPONSE )消息、 或者 X2基站配置更新 ( ENB configuration update ) 消息中。 进一步地， 本实施例中， 第一'■!、区所属的基站可以执行前述各方法 实施例或后续各方法实施例， 或者后续各基站实施例中第一小区所述的 基站与接入第一小区的终端通信的各种方案。 本较佳实施例中， 第一小区、 第二小区和第三小区的范畴可以与上 一实施例相同， 这里不再赘述。 通过上述方案， 基站获取了相关联的第二小区和第三小区的信息， 并在自身中存储， 则后续可协助终端确定其接入的小区是否存在相关联 的小区， 或者可以协助接入第一小区的终端获取其能够探测到的第三小 区所关联的第二小区的信息，使得终端可以对关联的第二小区进行测量。 如图 3所示， 另一种小区测量方法实施例包括如下步骤： 步骤 301、 根据从第一小区归属的基站获取的第二小区位置信息和 接入上述第一小区的终端的位置信息，监测上述终端是否靠近第二小区。 上述第一小区可以为宏小区， 上述第二小区可以为与宏小区覆盖范 围内的小区或与上述宏小区相邻的且具有共同覆盖区域的小区，如 WiFi 热点小区， Lomo (支持低速移动的小站点， 或者叫 HIFI ) 小区， 动态 频谱共享 （Dynamic spectrum share, DSS)小区 （即可以将下行业务工作 在上行资源的小区， 如 FDD的上行载波或 TDD的上行子帧）， 或其它敖 ( Micro )小区， 微微（ Pico )小区， 射频拉远前端（ Remote Radio Head, RRH ) 小区， 中继 （Relay ) 小区等非宏小区。 本申请文件中所提及的终端靠近第二小区， 是指终端进入该第二小 区的覆盖范围， 或者与该第二小区的覆盖范围的距离在设定门限内。 步骤 302、 当监测到上述终端靠近上述第二小区时， 启动上述终端 对上述第二小区的测量。 本实施例中， 通过对终端与第二小区的位置信息的比较， 确定是否 启动终端对第二小区的测量， 一方面无需终端不断搜索 WIFI热点小区， 节省了终端的耗电； 另一方面， 由于对第二小区的测量不考虑第一小区 的信号质量， 在第一小区信号质量很好的情况下， 也能够根据位置信息 启动对第二小区的测量， 从而提高了测量的及时性， 为第二小区更加有 效地分流第一小区终端提供了可能性。 另外， 本实施例中， 通过从基站获取第二小区的位置信息数据， 无 需终端保存第二小区的数据， 一方面节约了终端的存储空间， 另一方面 确保了能够更加快速准确地获取终端位置附近的第二小区信息， 从而能 够更加快速准确地启动对第二小区的测量。 为描述方便， 本发明实施例的以下部分以第一小区为宏小区， 第二 小区为低功率节点 （LPN ) 小区为例进行阐述。 需要说明的是， 第二小 区并不仅限于低功率节点小区， 对于某些小区基站或小区节点的发射功 率并不低于宏小区， 但其在宏小区覆盖范围内， 或者相邻， 并用来对宏 小区所在网络分流的小区， 均属于第二小区。 上述图 3所示的流程可以由基站执行， 也可以由终端执行。 当由基站执行时， 上述步骤 301具体为： 上述宏小区归属的基站获 取上述终端的位置信息， 并获取自己中保存的 LPN小区的位置信息， 根 据上述获取的信息判断上述终端是否靠近 LPN小区。 当由基站执行时， 步骤 302中， 启动上述终端对上述 LPN小区的测 量可以包括： 上述宏小区归属的基站向上述终端下发通知消息， 通知上 述终端靠近了 LPN小区，以使得上述终端根据该通知消息启动对靠近的 LPN小区的测量；
或者启动上述终端对上述 LPN小区的测量可以包括：上述宏小区归 属的基站为上述终端配置测量配置信息， 并将配置的测量配置信息下发 给终端， 以使得上述终端根据上述配置的测量配置信息对上述靠近的 LPN小区进行测量。
当由终端执行时， 上述步骤 301具体为： 上述终端从基站获取 LPN 小区的位置信息， 并获取自己的位置信息， 根据上述获取的信息判断上 述终端是否靠近 LPN小区。
基站在宏小区的系统广播消息中， 可以广播全部或者部分宏小区覆 盖下的 LPN小区位置信息， 或者进一步广播相邻的 LPN小区的位置信 息。 则终端通过接收宏小区的系统广播消息， 可以获取 LPN小区的位置 信息。
终端自己的位置信息可以是通过终端的 GPS定位单元获取的，也可 以是终端采用其他定位技术获取的自己位置信息。
当由终端执行时， 步骤 302中， 启动上述终端对上述 LPN小区的测 量可以包括： UE自行启动对靠近的 LPN小区的测量。 则基站在广播 LPN小区的位置信息时， 同时广播用于测量 LPN小 区的信息，如 LPN小区的物理小区标识（ PCI )和/或全球小区标识（ GCI ), 终端可以根据广播的用于测量 LPN小区的信息启动对靠近的 LPN小区 的测量。
当由终端执行时， 步骤 302中， 启动上述终端对上述 LPN小区的测 量也可以包括： UE通知上述宏小区归属的基站上述 UE靠近 LPN小区 的信息， 并接收宏小区归属的基站反馈的 LPN小区测量配置信息， 根据 测量配置信息启动对靠近的 LPN小区的测量。
在启动终端对 LPN小区的测量后， 如图 4所示， 本实施例进一步可 以包括：
步骤 303、 当上述测量结果满足接入条件时， 将上述终端接入到上 述 LPN小区 。
具体地， 测量结果满足接入条件可以为： 上述 LPN小区的信号质量 能够满足上述终端的业务通信。由于在 LPN小区信号质量能够满足终端 业务通信的情况下， 即将终端接入到 LPN小区， 相对于现有技术中在宏 小区与 LPN小区信号质量达到一定差别后才将终端接入到 LPN小区的 方案， 终端接入 LPN 小区的可能性大大提高， 从而更加有效地实现了 LPN小区对宏小区的分流。 上述将终端接入到上述 LPN 小区可以包括： 将上述 UE接入上述 LPN小区， 并断开上述 UE与上述宏小区的信令连接。 上述将终端接入到上述 LPN小区也可以包括： 将上述 UE接入上述 LPN小区， 并保持上述 UE与上述宏小区的信令连接。 上述保持上述 UE与上述宏小区的信令连接后进一步可以包括： 上述宏小区归属的基站将 UE的所有业务都转移到上述 UE接入的 LPN小区。
上述保持上述 UE与上述宏小区的信令连接后进一步也可以包括： 上述宏小区把 UE的部分业务转移到 LPN小区； 具体地， UE可以在成功接入 LPN小区后， 发送一个信令告知基站 成功接入 LPN 小区的信息， 则基站根据业务的特性和宏小区的负荷情 况， 来决定是 4巴 UE的所有业务都转移到 LPN小区还是 4巴 UE的部分业 务都转移到 LPN小区。 上述方案中，根据从第一小区归属的基站获取的第二小区位置信息、 和接入所述第一小区的终端的位置信息， 监测所述终端是否靠近第二小 区， 当监测到所述终端靠近第二小区时， 启动所述终端对所述靠近的第 二小区的测量， 提供了与现有技术不同的小区测量方案。 进而， 当上述 方案应用于多小区覆盖重叠场景时， 一方面， 上述方案由于无需持续的 进行小区搜索， 降低了 UE耗电量； 另一方面， 在第一小区为宏小区， 第二小区为低功率节点小区情况下， 在宏小区信号较好时， 通过应用上 述方案也能够启动对低功率节点小区的测量， 启动测量不受宏小区信号 影响， 使得低功率节点小区对宏小区的分流更加快速有效。
以下通过几个示例性较佳实施例进一步阐述小区测量方法实施例的 方案。
示例性较佳实施例 1、 本实施例中， 由宏小区基站获取终端的位置信息， 并根据终端的位 置信息和自己获取的 LPN小区位置信息确定是否启动对 LPN小区的测 量， 并在满足接入条件时， 将终端接入 LPN小区， 从而实现更加有效地 分流宏小区中的终端。 在网络侧的数据库中保存了网络中 LPN小区的位置部署信息，位置 部署信息可以包括基站 ID (和 /或小区 ID ) 与位置信息的对应关系， 这 里的位置信息可以包括小区基站的经度、 维度和高度， 或者可以进一步 包括发射功率和 /或覆盖半径等范围数据。
Figure imgf000015_0001
上述 LPN 小区的位置部署信息可以是直接保存在基站和 /或基站的 后台设备中的， 和 /或是保存在一个专门的服务器中， 基站在需要位置信 息时， 通过查询该专门服务器获得。 当 LPN小区的位置部署信息保存在基站和 /或基站的后台设备中时 , 其中涉及的 LPN小区包括该基站覆盖范围内的 LPN小区， 或者包括覆 盖范围内的 LPN小区和相邻的 LPN小区。基站之间可以通过 X2口交互 位置信息， 如当新增一 LPN小区后， 新增 LPN小区基站可以通过向宏 小区基站发送 X2 SETUP REQUEST消息， X2 SETUP RESPONSE消息， 或者 X2 ENB configuration update消息来协助更新和完善 LPN小区基站 的位置信息。 上述 X2 SETUP REQUEST消息的内容可以如下表所示： IE/Group Name Presence Range IE type Semantics Criticality Assigned and description Criticality reference

可选的， 基站还可以通过收集 UE的测量报告， 根据测量报告中包 括的邻区位置信息辅助维护其覆盖范围内或相邻的 LNP 小区的位置信 息， 如加入新的 LNP小区位置部署信息等。 具体地， 如图 5所示， 本实施例在具体实施时， 包括如下步骤： 步骤 501、 宏小区基站获取 UE的位置信息和宏小区覆盖范围内的 LPN小区信息。
本步骤中也可以是宏小区基站获取 UE的位置信息， 以及， 宏小区 覆盖范围内和与宏小区相邻的 LPN小区位置信息。
如图 6所示， 为本实施例的一种示例性应用场景。在该场景下， LTE 宏小区 1部署在频率 1上， LPN小区 2, 如图中的 LOMO小区部署在该 宏小区覆盖范围内的频率 2上， 该 LOMO小区基站为图中的 WIFI AP。 在 LTE宏小区（以下筒称宏小区 )基站中保存了 WIFI AP的 ID、 LOMO 小区 2的 ID以及 WIFI AP的位置信息。 本实施例以这里保存的位置信 息包括经度、 维度、 高度和覆盖半径为例进行阐述。
本步骤中，可以是宏小区基站周期性发起对 UE的定位，如 OTDOA 定位来获取 UE的位置信息。 也可以是终端周期性地向宏小区基站上报 自己的位置信息， 如具有 GPS功能的终端周期性通过 GPS功能获取自 己位置信息后， 上报给基站。
步骤 502、 宏小区基站根据 UE的位置信息和自身中存储的 LPN小 区的位置信息， 监控 UE是否靠近 LPN小区。 本步骤中， 判断 UE是否靠近 LPN小区， 即为判断 UE是否进入该 LPN 小区的覆盖范围， 或者是否与该 LPN 小区的覆盖范围在设定门限 内。 上述覆盖范围根据经度、 维度、 高度和覆盖半径计算。
步骤 503、监控到 UE靠近 LPN小区后，宏小区基站通过 RRC专用 信令通知 UE靠近 LPN小区，该信令中携带靠近指示，靠近指示中包括， UE靠近的 LPN小区的 PCI和 /或 GCI, 或者进一步包括： 靠近小区的类 型、 靠近小区归属的基站节点的 ID、 靠近小区归属的基站节点的类型中 的任意一项或多项。
本步骤中， 基站也可以通过发送给 UE 的介质访问控制控制信令 ( Media Access Control Control element, MAC CE )携带上述靠近才旨示。
步骤 504、 UE接收包括靠近指示的信令， 根据信令中的靠近指示启 动对靠近的 LPN小区的测量。 这里测量的参数包括： 小区的信号强度和 /或信号质量。
本步骤中， 如果终端对 LPN 小区进行测量的射频是独立的射频， UE开启该 LPN小区对应的射频， 对这个 LPN小区的测量。 如果终端对 LPN小区进行测量的射频是和其他小区是共享的射频， 则 UE移动中心 频点， 实现对其他小区和这个 LPN小区的测量； 和 /或 UE在已打开的射 频上启动时间间隙 （GAP ) 测量该 LPN小区。 步骤 505: UE对测量的 LPN小区的信号强度和 /或信号质量进行监 测， 当监测到信号强度和 /或信号质量满足接入条件时， UE接入测量的 LPN小区。 本步骤中，接入条件为 LPN小区的信号强度和 /或信号质量满足 UE 正常业务通信的要求。 具体地， UE 中设定信号强度门限和 /或信号质量 门限， 当信号强度满足信号强度门限和 /或信号质量满足信号质量门限 时， 则信号强度和 /或信号质量满足 UE正常通信的要求。 具体的门限取 值可以为 -65dbm 本步骤中， 如果 LPN小区对应的射频是独立的射频， 则 UE接入测 量的 LPN小区为 UE直接在该 LPN小区对应的射频上接收数据； 否贝 ij , UE 通过向宏小区基站 （即源基站）发送测量报告发起异频或异系统切 换流程接入 LPN小区，具体的切换流程可以参考 3GPP协议 36.300中提 供的切换方案实现。
此外， UE接入 LPN小区后， 可以断开与宏小区的连接， 也可以保 持与宏小区的连接。 在保持与宏小区的连接的情况下， 可以是 UE 通知宏基站其接入 LPN小区后， 宏基站把 UE的所有业务都切换到 LPN小区， 或者宏基站 将 UE的部分业务都切换到 LPN小区。 具体地， UE接入 LPN小区后， 保持和源小区的信令连接， 并发送一个信令告知宏基站， 宏基站可以根 据 UE业务的特性和 /或宏基站的负荷情况， 来决定是把 UE的所有业务 都切换到 LPN小区还是把 UE的部分业务切换到 LPN小区。 具体业务 特性的选择和负荷门限的确定根据网络的具体情况确定。 如， 银行业务 等安全性要求比较高的业务， 依然在 LTE网络中传送； 而上网， 游戏等 业务， 可以在这 LPN小区内发送。
在保持与宏小区的连接的情况下， 也可以是由终端向用户提供人- 机界面供用户选择将 UE的所有业务都转移到 LPN小区， 还是把 UE的 部分业务转移到 LPN 小区， 此后终端根据用户的选择与宏基站和 LPN 小区基站通信进行业务切换。
步骤 506、 LPN小区基站获取终端的位置信息， 并根据 UE的位置 信息和自己中存储的 LPN小区位置信息， 监控 UE是否离开 LPN小区。
LPN小区基站中会保存该 LPN小区的位置部署信息，位置部署信息 的具体内容， 以及本步骤的具体实现参考步骤 501和步骤 502, 本步骤 中离开 LPN小区的条件与靠近 LPN小区的条件相反， 即到达 LPN小区 的覆盖范围边界， 或者在覆盖范围内距离边界设定距离。
步骤 507、 LPN小区基站监控到 UE离开 LPN小区后， 向 UE发送 离开指示。
上述离开指示可以通过 RRC专用信令或者 MAC CE携带， 离开指 示的具体内容可以包括： 离开的 LPN小区的 PCI和 /或 GCI。 步骤 508、 UE接收到离开指示后， 根据指示中的 PCI和 /或 GCI停 止对 LPN小区的测量并断开与 LPN小区的连接。
具体地， 本步骤中， 如果 LPN小区对应的射频是独立的射频， UE 就直接关闭在这个该 LPN 小区对应的射频上接收数据和测量； 否则， UE通过向 LPN小区基站 （即源基站 )发送测量报告发起异频或异系统 切换流程切换到宏小区， 并停止对 LPN小区的测量。 具体的切换流程可 以参考步骤 505实现。 在本实施例中， 可替换地， 步骤 503中， 在监控到 UE靠近 LPN小 区后， 宏小区基站也可以直接下发测量控制信息给 UE, 启动 UE对靠近 的 LPN 小区的测量。 测量控制信息中携带测量对象信息， 如小区 CPI 或 CGI, 或者进一步包括测量量和 /或测量上报配置信息。 则在步骤 404 中， UE接收到测量控制信息后， UE就根据测量控制信息启动对靠近的 LPN小区的测量， 如果测量控制信息中包括了测量量， 则 UE根据该测 量控制信息中的测量量如信号强度和 /或信号质量， 进行测量； 否则， 与 本实施例前述部分相同地， UE测量上述 LPN小区的信号强度和 /或信号 质量。 对应地， 在步骤 507中， LPN小区基站监控到 UE离开 LPN小区 后， 可以向 UE发送停止测量指示， 该指示中包括停止测量的对象， 即 LPN小区的 CGI或 CPI; 则在步骤 508中， UE根据测量停止指示停止 对 LPN小区的测量并发起切换。 本实施例中， 可替换地， 步骤 505中， 当监测到信号强度和 /或信号 质量满足接入条件时， UE将测量的 LPN小区的信号强度、 信号质量和 测量事件中的任意一项或多项报告给宏小区基站， 宏小区基站根据 UE 上报的信息确定是否让 UE接入靠近的 LPN小区， 当确定让 UE接入靠 近的 LPN小区后， 发送消息通知 UE, UE接收到通知后接入 LPN小区。 本较佳实施例中， 通过对终端与 LPN小区的位置信息的比较， 确定 是否启动终端对 LPN小区的测量， 一方面无需终端不断搜索 WIFI热点 小区， 节省了终端的耗电； 另一方面， 由于对 LPN小区的测量不考虑宏 小区的信号质量， 在宏小区信号质量很好的情况下， 也能够根据位置信 息启动对 LPN小区的测量， 从而提高了测量的及时性， 为 LPN小区更 加有效地分流宏小区终端提供了可能性。 进而， 由于在 LPN小区信号质 量能够满足终端业务通信的情况下， 即将终端接入到 LPN小区， 相对于 现有技术中在宏小区与 LPN 小区信号质量达到一定差别后才将终端接 入到 LPN小区的方案， 终端接入 LPN小区的可能性大大提高， 从而更 加有效地实现了 LPN小区对宏小区的分流。 示例性较佳实施例 2:
本实施例中， 由终端通过宏小区基站获取网络侧数据库中存储的 LPN小区位置信息， 并将其与自己的位置信息进行比较， 确定是否启动 对 LPN小区的测量， 并在满足接入条件时， 终端接入 LPN小区， 从而 实现更加有效地分流宏小区中的终端。
如图 7所示， 本实施例在实现过程中， 包括如下步骤： 步骤 701、 宏小区基站在系统广播消息中， 广播全部或者部分本宏 小区覆盖下的 LPN小区位置信息， 或者进一步广播相邻的 LPN小区的 位置信息。 步骤 702、 UE获取上述系统广播消息中的 LPN小区的位置信息， 并通过定位技术获取自己的位置信息， 根据自己的位置信息和从基站的 广播消息里获得 LPN小区的位置信息进行比较，监控自己是否靠近某个 LPN小区。
具体的比对方案参考前述步骤 502实现。 区别在于， 本步骤中， 如 果管波消息中包括多个 LPN小区的位置信息， 则 UE需要将自己的位置 信息逐个与各 LPN小区的位置信息进行比较。 步骤 703、 UE监控到自己靠近某个 LPN小区后， 对该 LPN小区的 信号强度和 /或信号质量进行测量。
本步骤中， UE对该 LPN小区的信号强度和 /或信号质量进行测量的 方案参考前述步骤 504实现。
此后的步骤 704与前述步骤 505相同， 并且类似地， 也可以采用上 一示例性较佳实施例中步骤 505的替换步骤。 步骤 705、 UE获取自己的位置信息， 根据获取的位置信息和接入的 LPN小区的位置信息进行比较， 监控自己是否离开该 LPN小区。
本实施例中， UE可以实时地通过自身的 GPS单元获取自身的位置 信息， 也可以周期发起网络定位， 如发起 OTDOA, 获取自身的位置信
步骤 706、 UE监控到自己离开 LPN小区后， 停止对 LPN小区的测 量， 并断开与 LPN小区的连接。
本步骤中具体停止测量以及断开连接的方案， 可以参考前一示例性 较佳实施例中的步骤 508实现。
可替换地， 本实施例步骤 703中， UE监控到自己靠近某个 LPN小 区后， 也可以不直接启动对 LPN小区的测量， 而是将靠近某个 LPN小 区的信息通过信令告知宏小区基站。 宏小区基站收到该信令后， 为 UE 配置测量控制信息， 并下发给 UE, 启动 UE对靠近的 LPN小区的测量。 测量控制信息中携带测量对象信息， 如小区 CPI或 CGI, 或者进一步包 括测量量和 /或测量上报配置信息。 UE接收到测量控制信息后， UE就根 据测量控制信息启动对靠近的 LPN小区的测量，如果测量控制信息中包 括了测量量， 则 UE根据该测量控制信息中的测量量如信号强度和 /或信 号质量， 进行测量； 否则， 与本实施例前述部分相同地， UE 测量上述 LPN小区的信号强度和 /或信号质量。 对应地， 在步骤 706中， UE监控 到离开 LPN小区后， 可以向 LPN小区发送信令， 将离开该 LPN小区的 信息通过信令告知 LPN小区基站， 则 LPN小区基站向 UE发送停止测 量指示， 该指示中包括停止测量的对象， 即 LPN小区的 CGI或 CPI; 则 UE根据测量停止指示停止对 LPN小区的测量并断开与 LPN小区的连 接。
本较佳实施例中， 通过对终端与 LPN小区的位置信息的比较， 确定 是否启动终端对 LPN小区的测量， 一方面无需终端不断搜索 WIFI热点 小区， 节省了终端的耗电； 另一方面， 由于对 LPN小区的测量不考虑宏 小区的信号质量， 在宏小区信号质量很好的情况下， 也能够根据位置信 息启动对 LPN小区的测量， 从而提高了测量的及时性， 为 LPN小区更 加有效地分流宏小区终端提供了可能性。 进而， 由于在 LPN小区信号质 量能够满足终端业务通信的情况下， 即将终端接入到 LPN小区， 相对于 现有技术中在宏小区与 LPN 小区信号质量达到一定差别后才将终端接 入到 LPN小区的方案， 终端接入 LPN小区的可能性大大提高， 从而更 加有效地实现了 LPN小区对宏小区的分流。 示例性较佳实施例 3: 本示例性较佳实施例中， 部署一个和 LPN小区基本同覆盖（本申请 文件中所提及的基本同覆盖是指第三小区的覆盖面积等于或略大于 LPN 小区， 如覆盖半径比在 1 :1至 1.1:1之间）的第三小区， 该第三小区的频 率与宏小区频率相同， 从而接入宏小区的终端可以直接接收到第三小区 的信号。
上述第三小区可以是一个实际的 LTE 小区， 也可以是一个虚拟小 区。 虚拟小区归属的基站在虚拟小区上仅发送同步信令和系统消息， 不 进行业务数据的调度。 如， 没有用于业务数据调度的 PDCCH和没有用 于发送下行业务数据的 PDSCH的发送。 第三小区的 PCI取自特定的一 组或多组第三小区 PCI。
UE中可以预先存储特定的第三小区 PCI组信息，也可以是 UE通过 接收宏小区基站的系统广播消息获取特定的第三小区 PCI组信息。当 UE 根据探测到的同步信令推出的 PCI属于这个特定的第三小区 PCI组时， 可以判断出存在一个第三小区， 从而异频率上有个与第三小区同覆盖的 LPN小区部署。 还可以进一步通过推出的 PCI, 确定出是具体哪个频率 上有 LPN小区部署， 即确定 LPN小区的频率信息。 本实施例中， 可以通过单独放置一基站的方式部署第三小区； 也可 以通过在 LPN 小区归属的基站上另外布置一个射频单元的方式部署第 三小区。
图 8示出了部署的第三小区为 LTE小区的一种场景，其中第三小区 为通过 WIFI AP部署的 LTE小区 3、宏小区为宏 LTE小区 1、 LPN小区 为通过 Pico AP部署的 LTE-LoMo小区 2。 图 8中， 通过 WIFI AP部署 的也可以是 LTE-LoMo小区 2, 而通过 Pico AP部署的为 LTE小区 3。 图 9示出了部署的第三小区为虚拟 LTE小区的一种场景，与图 8的 区别仅在于， 部署的第三小区为 LTE虚拟小区 3。 如图 10所示，本示例性较佳实施例在具体实现过程中，其流程具体 包括如下步骤： 步骤 1001、 接入宏小区的 UE进行同频邻区测量时， 探测是否获取 了第三小区的 PCL
具体地， 本步骤中， UE探测获取 PCI, 可以是 UE通过同频邻区测 量接收同频邻区的同步信令， 再根据接收的同步信令中的信息推导出 PCI。 具体根据同步信令推到 PCI 的方法为本领域技术人员所公知， 这 里不再赘述。
本步骤中， 接入宏小区的 UE判断探测到的 PCI是否取自特定的第 三小区 PCI组， 即是否属于特定的第三小区 PCI组， 即可以判定探测到 的 PCI对应的小区是否为第三小区， 如果探测到的 PCI对应的小区为第 三小区， 则可以确定终端靠近了第二小区。 步骤 1002、 探测到了第三小区的 PCI后， 对 LPN小区进行测量， 即对 LPN小区的信号强度和 /或信号质量进行测量。 本步骤中， 可以是 UE自行对 LPN小区进行测量， 如直接在所支持 的、 与第一小区异频的全部频率上进行测量， 或者根据自身中存储的信 息获取 LPN小区的频段信息， 再根据频段信息进行测量， 具体的实现方 案参考上述步骤 102中的相关描述。 UE对 LPN小区的信号强度和 /或信 号质量进行测量的具体实现方案参考上述步骤 504。
本步骤中， UE也可以不直接启动对 LPN小区的测量， 而是在探测 到了第三小区的 PCI后， 发送靠近指示给宏小区基站后， 由宏小区基站 为 UE配置对 LPN小区的测量配置信息，从而启动 UE对 LPN小区的测 量。 具体的实现方案参考上述步骤 102中的相关描述， 以及上述步骤这 里不再赘述。
步骤 1003、 UE对测量的 LPN小区的信号强度和 /或信号质量进行监 测， 当监测到信号强度和 /或信号质量满足接入条件时， UE接入测量的 LPN小区。 本步骤的具体实现参考前述步骤 505实现， 这里不再赘述。 步骤 1004、 接入 LPN小区的终端监控到自己离开 LPN小区后， 停 止对 LPN小区的测量， 并断开与 LPN小区的连接。 本步骤中， 终端通过监控接入的 LPN 的小区信号强度和 /或信号质 量， 根据是否： 小区信号强度低于设定的信号强度门限值和 /或信号质量 低于设定的信号质量门限值， 确定自己是否离开了 LPN小区。 本步骤中具体停止测量以及断开连接的方案， 可以参考前述步骤 508实现， 这里不再赘述。 本较佳实施例中，通过终端对是否存在与 LPN小区基本同覆盖的第 三小区进行探测， 从而确定是否启动终端对 LPN小区的测量， 提供了多 小区覆盖重叠情况下的小区测量方案。 进而， 一方面无需终端不断搜索 WIFI热点小区， 节省了终端的耗电； 另一方面， 由于对 LPN小区的测 量不考虑宏小区的信号质量， 在宏小区信号质量很好的情况下， 也能够 根据基本同覆盖的第三小区信息启动对 LPN小区的测量，从而提高了测 量的及时性， 为 LPN小区更加有效地分流宏小区终端提供了可能性。 进 而， 由于在 LPN小区信号质量能够满足终端业务通信的情况下， 即将终 端接入到 LPN小区， 相对于现有技术中在宏小区与 LPN小区信号质量 达到一定差别后才将终端接入到 LPN小区的方案， 终端接入 LPN小区 的可能性大大提高， 从而更加有效地实现了 LPN小区对宏小区的分流。 示例性较佳实施例 4: 本示例性较佳实施例中， 与上一示例性较佳实施例相同的是， 也部 署一个和 LPN小区 （即第二小区）基本同覆盖的第三小区。 第三小区的 具体部署方式参考上一示例性较佳实施例实现即可。 此外， 本示例性较佳实施例中， 还在网络侧保存第三小区与 LPN小 区的位置部署的关联信息 （即 LPN小区和第三小区的关联关系） 。 网络侧保存的上述 LPN小区与第三小区的关联信息，可以入下表所 关联对象 关联关系信息

小区 4, 小区 5 同覆盖
小区 7, 小区 9 相邻
示。该关联关系可以是直接保存在宏小区基站和 /或宏小区基站的后台设 备中的， 和 /或是保存在一个专门的服务器， 如操作管理维护系统
( Operation Administration and Maintenance , OAM )服务器中 , 宏小区 基站在需要关联信息时， 通过查询该专门服务器获得。
LPN 小区与第三小区的关联信息中涉及的 LPN小区包括宏小区覆 盖范围内的 LPN小区， 或者包括宏小区覆盖范围内的 LPN小区和宏小 区相邻的 LPN小区。 基站之间可以通过 Χ2口交互小区位置关联信息（即上述 LPN小区 与第三小区的关联信息） ， 如当新增一 LPN小区和 /或新增一第三小区 后， 新增小区所属的基站可以通过向宏小区基站（即， 第一小区的基站） 发送 Χ2 SETUP REQUEST消息， X2 SETUP RESPONSE消息， 或者 X2 ENB configuration update消息来协助更新和完善 LPN小区的信息和 /或 上述第三小区的信息， 这里的信息可以是位置信息， 则宏小区基站可以 根据接收的 LPN 小区的位置信息和第三小区的位置信息确定两小区关 联， 从而存储 LPN小区与第三小区的关联信息。 或者是上述新增小区的基站直接通过 X2口告知 LPN小区和第三小 区关联的信息给宏小区基站。 具体地， 新增小区的基站可以通过发送 X2 SETUP REQUEST消息， X2 SETUP RESPONSE消息， 或者 X2 ENB configuration update消息告知。 如图 10a所示， 本实施例具体实现过程中可包括如下步骤： 步骤 1011、 接入宏小区的 UE进行同频邻区测量时， 确定是否探测 到了第三小区的 PCI。 具体地， 本步骤中， UE探测获取 PCI, 可以是 UE通过同频邻区测 量接收同频邻区的同步信令， 再根据接收的同步信令中的信息推导出 PCI。 具体根据同步信令推到 PCI 的方法为本领域技术人员所公知， 这 里不再赘述。
UE中可以预先存储特定的第三小区 PCI组信息，也可以是 UE通过 接收宏小区基站的系统广播消息或专用信令获取特定的第三小区 PCI组 信息。 当 UE根据探测到的同步信令推出的 PCI属于这个特定的第三小 区 PCI组时， 可以判断出存在一个第三小区。
步骤 1012、 探测到了第三小区的 PCI后， UE发送靠近指示给宏小 区基站；
该靠近指示里包括第三小区 PCI。 步骤 1013、 宏小区基站收到靠近指示后， 根据自身保存的 LPN小 区和第三小区的关联关系， 获取对应的 LPN 小区信息， 并根据获取的 LPN小区信息确定测量配置信息。
上述 LPN 小区和第三小区的关联关系中， 第三小区的信息可以是 PCI信息， 也可以是第三小区的其他信息。 如果是第三小区的 PCI信息， 则宏小区基站直接根据靠近指示中的 PCI信息查询关联关系， 确定对应 的 LPN小区信息。 如果是第三小区的其他信息， 如 CGI, 则基站首先根 据靠近指示中的 PCI和自身中保存的第三小区信息获取对应的 CGI, 再 根据 CGI确定对应 LPN小区信息。
在确定对应的 LPN小区信息后， 基站根据该 LPN小区的频段 (关 联关系中的 LPN小区信息可以直接包括频段信息，也可以不包括频段信 息， 则基站根据 LPN小区信息， 如 CGI或 PCI和自身中保存的 LPN小 区信息与频段的对应关系确定频段信息）为 UE配置对 LPN小区的测量 配置信息， 从而启动 UE对 LPN小区的测量， 后续 UE根据测量配置信 息启动测量，接入第二小区的方案参考前述实施例实现， 这里不再赘述。
示例性较佳实施例 5:
本示例性较佳实施例中， 与上一示例性较佳实施例相同， 也部署一 个和 LPN小区 （即第二小区）基本同覆盖的第三小区， 并在网络侧保存 第三小区与 LPN小区的位置部署的关联信息 （即 LPN小区和第三小区 的关联关系） 。 这部分方案的具体实现参考上一示例性较佳实施例， 这 里不再赘述。
如图 10b所示， 本示例性较佳实施例在实现过程中包括如下步骤： 步骤 1021、 宏小区基站 （即， 第一小区的基站）给 UE配置周期性 测量配置信息；
周期性测量配置信息包括测量的频段、上报周期， 以及切换迟滞等。 这里测量的频率为宏小区的频段， 也即第三小区的频段。
步骤 1022、 接入宏小区的 UE根据上述周期性测量配置信息进行同 频邻区测量， 并将测量的结果周期性上报。
步骤 1023、 宏小区基站收到 UE的测量报告后， 如果报告中有第三 小区的信息，基站则根据自身保存的第三小区与 LPN小区的位置部署的 关联信息， 获取 LPN小区信息， 并根据获取的 LPN小区信息确定的测 量配置信息， 并配置给 UE, 以启动 UE对 LPN小区的测量。
后续 UE根据测量配置信息启动测量， 接入第二小区的方案参考前 述实施例实现， 这里不再赘述。 本步骤中， 基站中可以配置第三小区信息的集合， 当测量报告中的 第三小区的信息属于该集合时， 确定存在第三小区， 进而可以根据该第 三小区信息查询关联关系， 获取对应的 LPN小区信息。
基站中也可以不配置第三小区信息的集合， 则基站接收到测量报告 后， 查询上述关联关系中是否包括测量报告中上报的小区信息， 如果包 括， 则进而根据该小区信息确定关联的 LPN小区； 否则， 认为 UE没有 探测到第三小区， 可以不对该测量报告进行处理。 上述第三小区的信息可以是 PCI, 也可以是 CGI或其他信息。
上述示例性较佳实施例 4和 5中， 通过在网络侧存储第二小区和第 三小区的关联关系， 从而宏基站在确定出 UE探测到了第三小区后， 即 UE 到达了第三小区的覆盖范围后， 根据第三小区信息获取关联的第二 小区， 并向 UE下发测量配置信息， 从而启动 UE对第二小区的测量， 提供了多小区覆盖重叠情况下的小区测量方案。 进而， 一方面无需终端 不断搜索 WIFI热点小区， 节省了终端的耗电； 另一方面， 由于对 LPN 小区的测量不考虑宏小区的信号质量，在宏小区信号质量很好的情况下， 也能够根据基本同覆盖的第三小区信息启动对 LPN小区的测量，从而提 高了测量的及时性，为 LPN小区更加有效地分流宏小区终端提供了可能 性。 进而， 由于在 LPN小区信号质量能够满足终端业务通信的情况下， 即将终端接入到 LPN小区， 相对于现有技术中在宏小区与 LPN小区信 号质量达到一定差别后才将终端接入到 LPN小区的方案，终端接入 LPN 小区的可能性大大提高，从而更加有效地实现了 LPN小区对宏小区的分 流。 上述各方法实施例中， 相关部分的方案可以在各实施例间参考或替 换实现。 本领域普通技术人员可以理解， 实现上述方法实施方式中的全部或 部分步骤是可以通过程序来指令相关的硬件来完成， 上述的程序可以存 储于计算机可读取存储介质中， 该程序在执行时， 可以包括前述本发明 基于 MIP技术的通信方法各个实施方式的内容。这里所称得的存储介质， 如： ROM/RAM、 磁碟、 光盘等。 本发明实施例还提供了一种终端， 如图 11所示， 该终端包括： 探测单元 111 , 用于探测第三小区的信令， 上述第三小区为与上述 终端接入的第一小区同频的小区； 测量单元 112,用于在上述探测单元 111探测到第三小区的信令后， 对第二小区进行测量， 上述第二小区为与第三小区相关联的， 且与第一 小区异频的小区。 上述第一小区可以为宏小区， 则上述第二小区为上述宏小区覆盖区 域内的小区或为与上述宏小区相邻的小区。 上述第二小区与第三小区相关联可以为： 上述第二小区与上述第三 小区同覆盖， 或者上述第三小区的覆盖范围包括上述第二小区的覆盖范 围；
